Arizona Trucking Association President Tony Bradley says one good thing may have come out of the closure of a section of Interstate 10 this week – it could point up the need to fix the nation’s infrastructure.

The Arizona Department of Transportation says cameras being mounted on poles at several locations along rural freeways are to monitor commercial trucks' compliance with regulations and weight restrictions, not to catch speeders.

A rash of deadly wrong-way crashes on Phoenix-area freeways has led the Arizona Department of Transportation to research technology that would detect a car driving the wrong direction and send alerts to overhead freeway signs and police.

Millennials’ preferences for getting around have facilitated the end of the “driving boom” and regional transportation planners will have to adjust to account for this new reality, according to a recent report.
